My present invention has reference to a fly screen for window frames,and the primary object of the invention is the provision of meanswhereby flies which have entered the room can be driven out through anormally closed opening in the lower portion of the screen.

A further object is the provision of-a fly screen that includes aframehaving an up per reticulated portion and a lower portion closed bytransverse panels, oneof said panels being slidable over the other panelto provide an opening therebetween and through which opening flies in a.room may find an outlet.

To the attainment of .the foregoing the invention consists in theimprovement hereinafter described and definitely, claimed.

In the drawings:

Figure 1 is a front elevation of the improvement.

Figure 2 is an enlarged sectional View approximately on the line 2-.2 ofFigure 1.

Figure 3 is a similar sectional view approximately on the line 33 ofFigure 1.

The improvement contemplates the em ployment of a substantiallyrectangular frame 1 of a size to fit in the sash opening of a'windowcasing or is of a size to be arranged alongside of the casing andmounted 011 runners that are fixed to the casing for vertical slidingmovement. The outer face of the frame, in a line with the inner edgesthereof,

has tacked thereonbeads 2, and the frame includes in addition to its topand bottom rails an interine'diaterail 3 disposed a slight but suitabledistance above'its lower rail 4 A strip of molding 5 is tacked to theouter face of the outer rail 3 and there is secured to the rails andstiles of the frame at and above the rail 3, a wire mesh 6. The mesh,

of course, has its edges covered by the mold-;

numeral 8 and both the lower rail 4 and the confronting faces of therail3 have their faces beyond the said grooves 8 provided with proections or longitudinally extending ribs 9, respectively, the said IlbShavlngtheir outer ends providing the innerwalls of longitudinallyextending grooves'1'0."'The ribs 9, at the portions thereof arrangedover the outer end of the plate or panel 7' are outinwardly, as at11,'toward the said panel 7 and from thence the inner-walls provided bythe said ribs are cut: angularly, as at 12, the

reducedendlof the angle portions being-in a 7 line with the end of theplate or panel 7 and 1 the second or widened en'd'18 terminating in aline with the inner wall provided by the "end; of the panel inreality'terminates in a line with the reduced shoulders 14 provided" G5 grooves1O, or in otherwords, the thickened by the angle portions of theribsandoonsequen-tly thegrooves or channel'sS pass through the-ribs 9 betweenthe shoulders lland 1-4.3

Theribs 9 between the shoulders llhand the widened ends 13 thereof,together with the angle wall 12, provide the said-rails 3 and 4 withoppositely disposed angle depressions 15, and in these depressions thereis a transparent plate or panel 16 which normally is and is, therefore,in contact with the angle walls 12 provided by the ribs 9 and with theinner face'ofthe transparent plate or panelv 7. By graspingthe inner end'of'theplate '-received between oneof the stiles of the "frame 1 and-theshoulders 11 of the ribs 9 or-panel .16 an'd swingingfithe sa-metoward fthe outer wall 17-providedby the groove '10, the said plate or panel 16'will be brought to a line with the groove and be slid-longie 1 tudinallytherein, thus uncoveringthe open ing between the end of the plate orpanel-7 and one of the vertical stiles of -the' frame 1.

When the panel 16 is thus moved any flies which may have congregated finthe wooing may be forced out ofthe-room through the opening left bythegpa nel '16. 'The improve- I ment n'ct only'kprovides forforcingflies outside of a room but both faces of the tra'nspar- I cutplates, or, paneled-Q and 7 maybe cleaned The manner in which the innerfaces of the panels may be cleaned is apparent. The slidable panel 16 isbrought against the outer wall 17 provided by the groove 10 which 5leaves a space between the panel and the ribs 9 sufiicient for thepassage of the cleaning rag which operateson the outer face of thepanel. By sliding the panel 16 in the guide grooves 10 to open positiona cleaning rag or 10 the like may be passed through the opening andalong the outer face of the panel 7 so that both the inner and outerfaces of the panels may be cleaned without necessitating the removalfrom the window casing. Having described the invention, I claim: 1. Afly screen for windows comprising a substantially rectangular framehaving a. transverse rail secured to its stiles above the lower rail ofthe frame, said frame having, a'wire mesh fixed to the transverse rail,and to the portions of the frame thereabove, a transparent panelsupported between the transverse rail and the lower rail of the frameand terminating a distance away from one of the stiles of the frame,said transverse and lower rails having their confronting 'faces providedwith outstanding longitudinal ribs and provided with grooves whose innerwalls are afforded by the edges of said 7 Walls, said ribs being cutangularly inward of the terminal end of the transparent plate, and fromthence cut angularly to the inner wall provided by the groove and onestile of the frame to afford both of the rails with alining anglepassages, and a transparent plate received in said passages, normallycontacting withthe inner face of the first named transparent. plate forclosing the opening between the fixed plate and one of the stiles of 40,the frame and movable in its channels and through the grooves to uncoverthe opening between the end of the fixed plate and the said stile of theframe.

2. A window screen comprising a substan- I tially rectangular framehaving a transverse rail secured to its stiles and above the lower railand a mesh secured to the uppermost rail and the lower portionof theframe, a fixed transparent panel between the transverse rail and thelower rail of theframe,

I said rails having their confronting faces provided with longitudinalgrooves, the inner Walls provided by which being beveled from one of theends thereof, and a slidable transparent panel normally received againstthe angle walls provided by the said portions of the grooves, wherebythe slidable transparent plates will normally cover the opening betweenthefiXed plates and one end of the frame'and the said slidabletransparent plate being movable into the restrictedpassages of thev'g'r'oovefor uncovering said opening' In testimony whereofI affix mysignature.
